Review: Hey. That's pretty good! - TLDR: If you're in it for the best DAC for music at this price, look elsewhere. If you're in it for a DAC for general use all around (Music, Movies, Games,) this may be the best thing for you under $250. [Update after nearly five months at the end!] Full Review: Imma start with the good. Those knobs. It drives me nuts, all the DACs and DAC enthusiasts insisting that there's just one, perfectly flat way things should be listened to. “If you want more bass, get headphones/speakers with more bass.” How about, I'm not made of money, and my already large collection still needs more variety. I do budget, but I'm all over the place within my budget. I have a drawer of "chifi" earbuds. A few Sony MH755s (the best bang for your buck if you're on a super low budget, too bad they're hard to find genuine, and the cables are short), Zero Audio Carbo Mezzo (ZH-DX220-C), those Action Pies with the dual drivers (which frankly sound better than I ever expected), Shure SE215, and a bunch of others I tested with these. By far this DAC works the best with the Zero Audios. I was shocked, as generally the Zero Audios weren't my favorite to begin with, but with this DAC they really shine. I've liked other budget DACs more for clear music with a good soundstage, FiiO primarily having some of my favorite so far. But the FiiOs are just boxes. They don't have these knobs. For music, I keep the bass and treble knobs at about 75% of their total capacity. But if I'm about to go watch a movie, rewatch Star Wars or something, that treble knob I turn down to 50%, and crank that bass up to about 90%. You feel like you're in a theater with that overcompensating sound system, and I just LOVE IT. This isn't the DAC you want for the highest quality music, but this is a very good DAC for someone who wants to tinker with the sound, and has a high priority for how they tweak their sound for movies and video games. Here's another great example. Far Cry 5, that sniper rifle is super loud. And the control for sound in that game is awful, the only option is to turn down the music. So I cranked the treble down to 25%, and it took the edge off the loud sniper while allowing me to keep my volume where it was. I cannot stress how useful the knobs can be. The only other DAC I know of that would do this well (but probably better) is the (I'm sorry, this is really the companies name:) Schiit Loki Equalizer, and that thing ALONE will set you back $200. It's just an equalizer. You would still need to buy a DAC on top of it! Maybe that's the best way they could market this, as a “gaming DAC” because I feel like gamers will appreciate this product for what it is a heck of a lot more than the hardcore music community, who will find this somewhat lacking. And that's not a knock on gamers, I'm just observing that gamers tend to be more in it for the maliable experience that pushes whatever media they are taking in more. Immersion. They don't care if it looks good on paper, they care that it makes the experience more intense. This DAC can add that but without horrible distortion, like the equalizers you'd find on “gaming sound cards” and it's half the price of some of those that I see people buying. Overall, it's a simple little plug and play DAC that looks nice on the shelf, does more than you'd expect, and doesn't break the bank. If you're more in it for mixed media, or you just want audio that sounds better than the bad thing you currently have but you don't need “the best” (whatever that really means) then just buy this sucker. UPDATE After almost five months: I've now paired this with the 1MORE Triple Driver inears, I'm sitting here listening to Above and Beyond's Group Therapy #372, and it struck me just how much my ears are tickled and pleased by this this combo. Absurdly bassy, yet very little distortion with that combo. I'm in listening bliss, and as such, I've decided to bump this thing up to a 5 star. I can't think of any accessory or part for my computer that's seemed to have done so much for so little. EDIT2: I swear the title didn't used to say "gaming DAC" and to be honest, while I KNOW I suggested it, this is not REALLY a gaming DAC, in that gaming DACs usually have weird sound positioning features this does not. Features involving positional audio enhancements, which to be clear, this does not have. As I said in the review above, if you enjoy the immersion of great audio, this will be great for games. But it doesn't have "conventional gaming DAC features." As a gamer who never plays competitive games anyway, I wouldn't want special positional audio features ANYWAY. I just don't want anyone reading this to think it has positional audio features when it does not. EDIT3: Still using this in February of 2022.
Review: Step up your PC Audio - Alright first and foremost this thing is awesome. Need to get that out of the way. I’ve been using this so far for about a week now nonstop and I’m in love. Before I was just swapping between my Bose QC headphones or some cheap IEMs plugged into my headphone jack off of my PC case and there was always a low audible “hum” and the sound was a bit flat if that makes sense. Heard that an audio DAC is a “game changer” from a few friends and ended up researching a few and came across this bad boy. Now let me just say yeah it’s pretty expensive just for PC audio (that’s my opinion I’m a cheapskate in this economy) but I genuinely feels like it’s worth every penny. The setup is a freaking breeze, no drivers needed, comes with all the cables, and is quite literally plug and play. From unboxing to using the DAC took me like two minutes and holy smokes is it awesome. Just with the bass & treble knobs at the stock halfway point, it already wakens my headphones to a whole new level! I spent the next 20 minutes just swapping through all my various headphones seeing how they sound using the DAC and I’m genuinely impressed. Did I mention it also got rid of the dreaded hum??? (Thank god) My favorite out of the headphones I tried was my cheap ole $15 IEMs that completely obliterated my Sony, Bose, Razer, and Skullcandy headphones. Now don’t get me wrong , none of those are “audiophile” headphones nor am I an audiophile but just from a regular ole normal dudes perspective, the combination of the DAC and the cheap IEMs had amazing clarity in vocals and all notes sounded crisp and my favorite is the BASS. These lil ole IEMs plugged directly into my PC had little to no bass, NOW they’re freaking super charged and especially with the adjustment knobs they sound freaking amazing. I keep my knobs both at 75% with volume around 50% and oh my god I’m never going back. Between listening to all types of music such as Rap, EDM, and classic rock im genuinely so impressed. Now for my gamers out there, this DAC doesn’t add any extra audio delay, the sounds are crisp and detailed allowing you to hear more than not having the DAC. From playing League, POE2, COD, and Fortnite I am genuinely so impressed by this DAC. I know I know, I’ve only had this DAC for a week, so I can’t really comment on the durability or longevity of the item, but I will absolutely update my review as time goes on!

### ⭐⭐⭐⭐ Great value for money
*by A***M on December 15, 2020*

My unit had an audible hissing sound (white noise) that was more pronounced on the left channel than on the right. The hiss was always there when the unit is connected, regardless of chosen input, or if it is usb powered from the PC or directly from a power socket. After contacting Fosi support I was assured these units do have white noise and that it may be more pronounced in certain headphones. I later changed from my low impedance headphones (32 Ohm HyperX Alpha's) to a medium impedance headphone (150 Ohm Sennheiser 58x Jubilee's), and on the higher impedance phones the hissing is barely noticable - so much better performance there. Pros: 1. Good sound quality, clear and loud, especially for the price. 2. Much smaller and lighter then I expected it to be. I can take this in my backpack with my laptop to have good quality sound on-the-go. 3. Physical bass and treble eq that works very well. 4. High quality materials, especially the knobs (!) - bass and treble knobs have tactile "clicking" when turned, the volume knob has a smooth turn operation. All knobs are from metal, heavy, and feel very high quality. I greatly appreciate this. 5. Lots of connectivity options - IN usb / opt / coa, OUT front 3.5mm headphone jack or back RCA. 6. True plug&play - Easiest setup I had. Cons: 1. White noise. Especially noticeable in low impedance headphones. 2. Left and right channels differ slightly (white noise at very different levels between them), so it may not be very balanced. 3. Cannot compete with DAC/AMPs above the 100$ range in sound quality (is that even a con...?)
